Ciao Jeanmarc, as discussed previously in another post, i finally tryed to update my metern 0.8.2.7 that was working with virtmet to metern 0.8.3.2
the update works well also adapting with reqsdm to calling DS device, SDM device and so on...
the problem is that virtmet is no working.
the problem i think that is in /metern/scripts/metern.php
with the last version of metern 0.8.2.7, to use virtmet, i do in this way:

Hi JM, yes, i understand completly what you mean!
i think that virtmet should be rewrite to match the new code of metern...i'm not able do to, and for sure i wouldn't ask to you to do that
but we was talking about i still have 0.8.2.7 and i explain that the reason behing is because that is the last version where i was able to adapt virtmet
if i use a new virtual meter, to have consumption split on two different time during a day i have to start counting from zero?
last question: the /metern/program/meter.php that i use to export consumption in 123solar is also to completly rewrite?
yesterday i tested mine, but didn't work after upgare to last version
thanks for sugestion!
Regards
